Casting nozzle with multi-stage flow division

摘要

A method and apparatus for flowing liquid metal through a casting nozzle includes an elongated bore having an entry port and at least two exit ports. A first baffle is positioned proximate to one exit port and a second baffle is positioned proximate to the other exit port. The baffles divide the flow of liquid metal into two outer streams and a central stream, and deflect the two outer streams in substantially opposite directions. A flow divider positioned downstream of the baffles divides the central stream into two inner streams, and cooperates with the baffles to deflect the two inner streams in the same or different direction in which the two outer streams are deflected.
